A revised edition of Petzoldt’s guide designed for anyone who ventures into the wilderness. Conservation is the theme: of the individual, of equipment, and of the environment. Clothing, equipment, and rations are thoroughly discussed, along with the necessity of good expedition behaviour. There are chapters on trail techniques, camping for conservation, and basic climbing, and more specialized information on snow techniques and winter mountaineering. Reading of topographic maps is also included. Detailed illustrations supplement technical material such as knots and use of climbing ropes; and there is valuable appendix material, including checklists of equipment, clothing, and recipes.
